• Question 221:

  Which of the following best describes the impact of an RP failure in a PIM ASM network?

  A. All existing multicast traffic is stopped immediately, as the PIM ASM network must have an RP to transmit the multicast traffic.
  B. The multicast traffic will be impacted, but not immediately, as multicast routers will not discover the RP failure until the keep alive timer expires.
  C. No impact at all, as an RP is not required in a PIM ASM network.
  D. The traffic is not impacted if the multicast traffic flows have already been established, and the traffic flow does not involve the RP in the path.
  D. The traffic is not impacted if the multicast traffic flows have already been established, and the traffic flow does not involve the RP in the path.
